A COPY statement can appear in the source text anywhere a character string or a separator can appear.
INCLUDE
The INCLUDE statement inserts declarations or statements into a source program.

EXEC SQL
INCLUDE MEMBER
END-EXEC
The member can contain any host language statements and any SQL statements other than an INCLUDE statement. In COBOL, INCLUDE member-name must not be specified in other than the DATA DIVISION or PROCEDURE DIVISION
NOTE:
- So INCLUDE can also have just COBOL statements like COPY (Copybook) and can be used in place of COPY in a COBOL program.
- Details in INCLUDE member is replaced at Precompile time while statements in COPY member are replaced in Compilation time.
- REPLACING option can be used for COPY and not for INCLUDE
